When somebody asks to be hired in a company, the company if
disagree to employ him must send the rejected employer a letter
with explanation why he was rejected.

Now potential employers may only tell fortunes why their
employment was rejected.

After adoption of this law the employers will better know the
labour market and this surely will lead to decreased unemployment
and overall improvement of the labour market.

I suggest to create the specialized bureaus/agencies which would
be a intermediary between a potential employer and a potential
employee. Employers would send letters (or emails) with their
employing proposal to such agencies and then the agency would
follow the letters …
